Areaface is a new Twitter and Google Maps mashup that lets you find Twitter users near any address. The application is very simple to use; you can either just click on the map or you can use the Google Maps search box to find a location. Area Face then loads in the profile pictures of twitter users near that location.
When you roll your mouse over any of the profile pictures the latest tweet by that person is shown. Areaface is a great way either to find people who Twitter near you or to find out what people are talking about at a given location.
